FIG. 5 is a flow chart showing the detailed procedure of the freeze setting process subroutine of step S5 of FIG.

First, it is determined whether or not any of the display switches 11 has an on event (step S11). When there is no on event, this subroutine processing is terminated, while one of the switches is turned on. When there is an on-event, it is determined which switch caused the on-event (step S12).

When the cursor switch 11 ₁ is pressed in the determination in step S12, the cursor 21 on the screen is moved in the direction in which the cursor switch 11 ₁ is pressed, and the parameter number of the move destination is secured in the RAM 6. After the data is stored in the area PN (step S13), this subroutine processing is ended. Here, a number is assigned to each parameter displayed on the panel display 3 of FIG. 4, and the number is stored in the area PN. Hereinafter, the contents of the area PN will be referred to as parameter number PN.

[0031] In the determination in step S12, YES when the switch 11 ₂ is pressed, the "□" of the previous parameters in which the cursor is located 21, denoted by "V" indicates that the freeze setting is performed (FIG. 4), parameter number PN
After the freeze flag FF (PN) indicated by is set ("1") (step S14), the present subroutine process is ended.

Furthermore, if it is determined at the step S12, when the NO switch 11 ₃ is pressed, it erases the "V" in "□" parameter for the position of the cursor 21, the freeze flag FF indicated by the parameter number PN (PN) is reset (“0”) (step S1
5) After that, this subroutine processing is ended.

First, the number corresponding to the pressed switch among the registration memory designating switches 13 _{1 to} 13 ₄ is stored in the area RN (step S21). here,
Each registration memory designation switch 13 _{1 to} 13 ₄
Is assigned a predetermined number, and the assigned number is stored in the area RN secured in the RAM 6.

Next, it is determined whether or not the memory switch (MSW) 13 ₅ is pressed (step S22), and when it is pressed, the panel setting currently set in the registration memory area indicated by the area RN is set. After writing the data (step S23), the present subroutine process is terminated. That is, as described above, the memory switch 1
When any of the registration memory designating switches 13 _{1 to} 13 ₄ is pressed while pressing 3 ₅ , the current panel setting data is stored in the registration memory area.

On the other hand, if it is determined in step S22 that the memory switch 13 ₅ is not pressed, that is, if any one of the registration memory designating switches 13 _{1 to} 13 ₄ is pressed, the process proceeds to step S24. Whether or not the freeze switch (FREEZE) 14 is on is determined by the value of the freeze function setting flag FS. Here, the freeze function setting flag FS is a flag for determining whether or not the freeze function is used, and the area of this flag FS is also secured in the RAM 6. Then, the value of the freeze function setting flag FS is "0".
When the freeze switch (FREEZE) 14 is pressed while the freeze function is in use, the freeze function setting flag FS is set (“1”), while the value of the freeze function setting flag FS is “1” (the freeze function is (Unused state)
When the freeze switch 14 is pressed at the time, the freeze function setting flag FS is reset (“0”). The LED 16 is controlled to be turned on or off according to the flag FS.

When the value of the freeze function setting flag FS is "0" in the determination in step S24, the freeze function is not used, and therefore all the registration data (panel data) stored in the registration memory area indicated by the area RN is displayed. After reading the setting data) and storing it in the panel memory (step S25), this subroutine process is terminated.

On the other hand, when it is determined in step S24 that the value of the freeze function setting flag FS is "1", the soft counter i secured in the RAM 6 is initialized (i =
1) Do. Here, the counter i is a counter for searching the setting states of all the freeze flags FF (i) in the freeze flag table FFT.
The count range of is the number of freeze flags FF () stored in the freeze flag table FFT. That is,
In this embodiment, the count range is "1 to N" (see FIG. 6).

In the following step S27, the value of the freeze flag FF (i) indicated by the counter i is determined,
When the value is "0", that is, when the parameter corresponding to the freeze flag FF (i) in the registration data indicated by the region RN is not frozen, the parameter is stored in the panel memory (step S28), while When the value of the freeze flag FF (i) is "1", that is, when the parameter is frozen, step S
28 is skipped and the process proceeds to step S29.

In step S29, it is determined whether or not the counter i has finished counting the range to be counted, and when the counting is finished, this subroutine processing is finished, while
When the counting is not completed, the counter i is incremented by "1" (step S30), and then the step S
Returning to 27, the above processing is repeated.

As described above, according to this embodiment,
Since it is possible to specify whether or not to freeze by specifying the parameters in the registration data one by one, it is possible to make settings as the user desires and expand the range of opportunities to use the freeze function. Become.

In this embodiment, whether or not to freeze is set one by one for each parameter of registration data. However, the present invention is not limited to this. Alternatively, it may be set for each group and whether or not to freeze each group. At this time, one freeze flag FF () may be prepared for each set.

Further, in the present embodiment, the setting is made as to whether or not the parameters are frozen by designating the parameters one by one with the cursor. Alternatively, the range may be specified not only by the cursor but also by another input device such as a mouse.

Further, in this embodiment, a plurality of registration memories and one freeze flag table FFT are provided.
And RAM are secured in different areas of the RAM 6, and when the registration data stored in each registration memory is read and set in the panel memory, write control is performed by one type of freeze setting of the freeze flag table FFT. However, the present invention is not limited to this, and the registration memory may store the freeze setting information, that is, information such as the range of parameters to be frozen, together with the panel setting data. In that case,
Each time the panel setting data stored in the registration memory is read, the range of frozen parameters is switched.

Further, in the present embodiment, the registration for storing the entire panel setting has been described, but the present invention is not limited to this, and the present invention is limited to a part thereof such as voice data, automatic accompaniment data and automatic performance data. May be applied to the other.
